Application led November 23, 1912. Serial No. 733,061.

To all who-m 'it may concern: Y

13e it known that l, VILLIAM HEYCOCK RirriN, a subject of the VKingdomof Great Britain, residing at Central avenue, Leicester, in the countyof Leicester, England, manufacturer, have invented certain new anduseful improvements in Dough-Molding Machinery, of which the followingis a specification.

This invention relates to dough molding machinery in which pieces ofdough are progressively rolled or squeezed in a trough, the presentimprovements having for their object further mechanical means wherebythe pieces of` dough are progressively stretchech drawn down andtightened to the closing and partly turned around in a mannersubstantially resembling that of the hand. f

According tothe present invention a series of revolubie disks, cones orequivalent members are incorporated in the trough and these disksrevolve during the passage of the dough aroundV or along the trough andtuck or press Vdown the said'dough toward the closing and give apartturn, while at the Sametime tightening the dough so that Vit will standup well for proof-and not run outand make a squat loaf when baked.

According to one convenient form of the present invention a rotor andstator are employed to form an annular' channel and the disks may bemounted upon the face of either the rotor or stator or according toanother convenient arrangement the channel may be of a straight or arcshaped or other configuration.

n order that this inventionY may be clearly understood and readilycarriedinto practice, reference may be had to the appended explanatorysheet of drawings, upon which Figure l is a sectional elevation of adough molding machine constructed in accordance with one form of thepresent invention. Fig. 2 is an end view of another form of doughmolding machine, and Fig. 3 isa side elevation thereof. y

ln one embodiment `of this invention the stator 1 consists of anexternal ring fixed in a` horizontal plane and said ring is bolted,clamped, or otherwise secured to a suitable underframe `or substructure2.

Disposed concentrically within the stator f1 and mounted on theextremity of a vertical spindle or shaft v3 suitablyV fixed in theunderframe or substructure 2 is the rotor 4 and the external face orperiphery 5 of said rotor lies adjacent to the internal periphery 6 ofthe stator 1 and the lower portion 7 of the rotor a is curved outwardlyin such a manner as to form a trough between the said rotor -1 andstator 1. The rotor et is formed integral with a narrow sleeve or collar8 and said sleeve or collar, which embraces or takes a bearing upon thefixed spindle 3 is provided at its lowest extremity with a bevel wheelwhich meshes with a smaller wheel 10 keyed toa horizontally disposedspindle or shaft 11, and which latter spindle or shaft 11 is journaledin suitable bearings provided in the underframe or substructure 2. rlhisshaft or spindle 11 is provided at its outermost eX- tremity withsuitable pulleys or the like 12 in order to enable the machine to bedriven by any suitable motive power.

From the foregoing arrangement of spindles and gear wheels it will beunderstood that the rotor l can be revolved within the stator 1 byrotating or driving the aforementioned pulleys or the like 12.

Disposed vertically within the stator 6 and projecting slightly from theinternal face or periphery 'thereof are a series Vof rotatable circulardisks 13 each having a centralV spindle 1lwhich is journaledtransversely within the stator' 1, and said disks 13 are approximatelythe same diameter as the width of the face of the stator 1.

The external or projecting faces of the disks 13 are of somewhat conicalor convex formation while secured to the internal face of each of thesaid disks 13 is a gear wheel 15 and each gear wheel 15 is adapted tomesh with a horizontal gear or spur wheel 1G which takes a bearing or isjournaled around the aforedescribed sleeve 8 integral with or secured tothe rotor 4t.

Keyed or secured to a sleeve 19 loosely mounted upon the shaft 11 is afurther gear wheel 17 and this latter wheel is adapted to mesh with aseries of teeth provided on the underside of the horizontal spur wheel16.

The sleeve 19 is driven in the same direction as that of the shaft 11but preferably at a different speed andrin operation it will be seenthat upon rotating the said shaft 11 by means of the pulleys 12 therotor 4: is revolved as aforedescribed and upon rotating at the sametime the sleeve 19 by means of the pulleys 20 in the same direction'that of the shaft 11 the disks A131 are re'- volved through the mediumof the hori zontal and vertical gear wheels 16" and 17. Byjthisarrangement of gear wheels it will be seen that upon rotating the shaft11 and sleeve 19 in the same direction as aforementioned the bottoms orlower halves of the disks always travel in the same direction as thatofthe rotor t.

Ball thrust bearings 18 may be disposed' at positions along the sleeve 8and may be arranged between the extremities of the boss provided Von thehorizontal gear wheel 16 andthe bosses provided upon the rotor 1 andgear wheel 9. Also a third ball thrust race may be disposed between thebevel Wheel 9y and a suitable portion of the underframe or substructure2. The gear wheels 16,l 17, and 10 are so dimensioned as to enable thedisks 13 to revolve at a much greater speed than that ofthe rotor 4; aswell as .in the opposite direction to that of the said rotor.

The operation is as follows The dough is fed into the trough between therotoretV and stator 1 and rolled b'y the action of the rotor against theresisting action of .the stator until it is caught up or engaged by the`projecting face of a disk, the revolution of Ywhich stretches, drawsdown and tightens the dough toward the closing at the same time partlyturning it around, after which it is operated upon by the rotor f1 andsuccessive disks 13 in the same manner until at the end of the trough itis delivered withthe skincompletely stretched, drawn down', andtightened to the closing.'

In a modification of the present invention instead of arranging therevolving disks 13 in the stator 1 they may be mounted in the rotor flin which case the stator 1 would be provided with the curved `formation7 of the trough. I In this instance the rotor 21 is driven through themedium 'of a vertical and horizontal ,shaft having bevel wheels in meshand the gear wheels 15 preferably sel cured tothe extremities of thedisk spindles 1e are adapted to mesh witha toothed cir` cular rack whichis stationary or fixed. 'lhus it will be seen that upon the rotor l1being revolvedthe disks provided thereon are also rotated on account oftheir gear v'vheels engaging the circular fixed rack.

According to another fornro'f the present invention as illustrated inFigs; 2 and 3 the trough 1 is of y straight or substantially straightVconfiguration and the dough is fed in at the one extremity ,and leavesor is re-4 moved at the otherl extremity while means are provided formoving or passing the dough along the said trough, The disks 13 aredisposed adjacent to one another their faces projecting from a verticallongitudinal disk frame 21, the central spindles of suchA disks taking abearing in this frame. Carried .by a suitable substructure or underframe22 are tvvo cylindrical rollers or drums' 23 andthese rollers or drumscarry an' endless band 24 which is disposed longitudinally before theroW of disk. facesl and thelconstructicnof the substructure 22 ispreferably such that thedrums 23 together with theAk endless bandl 211incline away `from the disks 13 so leaving a channelv 1 of somewhatV-formation. ,Suitable gearingmechanism is provided for` driving thedisks 13 as also the drums 23 and such disks 13 are preferably driven ata higherl speed than that of thedrums 23. Thus in operation upon'` thedough being fed into one extremity of the trough I1-` same is carriedalong bythe endless band 241 While the disks 13 ,revolveA and tuck orlpressV same downwardly, and so tighten the dough.

It will be' obvious that if desired the trough 1 neednot be straight inconfiguration but may be of arc formation or of other suitable shape. sl y To Fmore partieulariz@ the spindley 25 of the extreme disk maybecontinued onwardly and be provided with a pulley` or pulleys 26 on itsextremity and at ajposition somewhere along its length a further pulley27 is in- V- corpo'rated'. Fromthislfurther pulley 27 a series ofpulleyvsv23 maybe driven andthis series are disposed toward the bottomof the substructure or underframe 22 and from A these' series of pulleys2 8Uthe disks 1 3 may be driven by means ofV endless belts asillustrated irl-Fig. 3.

In order tol drive the drums 23 of the endless band 241 a diagonallydisposed shaft l 29 may be incorporated and such shaft-may be providedvvithztwo gearvvheels 3 0 and V31 which, mesh in one instancev with agear Wheel 32 on the driving disk spindle 25 and in the other instancewith a gear Wheel 33 onan extended portion of the shaft of one of thedrums or cylinders23 vand the gearwheels 32, 30; 31 and 33 arepreferably of such dimensions that .the disks 13 revolve faster than thedrums 23 as afore stated.

In operation it will.. be noticed i that upon the pulley 26 beingdriven, the entire series of disks 13 are driven as also is the endlessVband 24 through the aforementioned shaft mechanism.

The drums-.or cylinders 23 may be of external configuration;cylindrical, conical, or curved according to the shapeorsection of thetrough desired.
